Fast, Automated Optics System Confirms Extrasolar Planet Every 3 Minutes

by on August 20, 2014
A team led by principal investigator Christoph Baranec from University of Hawaii’s Institute for Astronomy and project scientist Nicholas Law from UNC at Chapel Hill runs an extremely successful fully automated survey of extrasolar planetary candidate targets identified by the Kepler space telescope, using a ground-based adaptive optics 60-inch telescope at Palomar. In just 36 […]

Crayfish Neurogenesis: Brain Cells Do Not Self-Renew And Must Come From Circulating Blood Cells

by on August 20, 2014
Scientists led by Professor Barbara Beltz from Wellesley College in Massachusetts and Dr. Irene Söderhäll from Uppsala University in Stockholm, have discovered an example where adult neurons are generated from stem cells in other tissue types, specifically that of circulating blood cells produced by the immune system. The experiments were performed on a crayfish model […]

Neural Patterns Show Odor Detection Is Like Picking Up Voices At A Noisy Cocktail Party

by on August 19, 2014
A team of scientists led by Professor Venkatesh Murthy at Harvard Medical School’s Department of Molecular and Cellular Biology, found that odor molecules activate specific patterns of neurons, and that the ability of a mouse to distinguish between a learned, target odor and random, background odors, depends on the strength of neural pattern overlap between […]

Rare Observation Of Fast X-Ray Blurring Around Markarian 335 Black Hole

by on August 19, 2014
NASA’s NuSTAR satellite witnessed an extremely rare event around a supermassive black hole: in a matter of days, its compact X-ray emitting corona tightened up around the center, better illuminating the accretion disc around it but showing a drop in brightness due to the intense light-bending black hole gravitational field. Subsequent observations by Professor Fiona […]

Spatial Attention, A Right Hemisphere Skill, Remains Unchanged Throughout Aging

by on August 19, 2014
At the University of Adelaide, Dr. Joanna Brooks, Visiting Research Fellow for the University’s School of Medicine and School of Psychology, discovered through a research study that the part of the brain responsible for spatial attention remains unchanged as the brain ages. She recruited sixty people of varying age groups, and measured their responses to […]

Genetic Switch Found For Foxp3 Which Maintains T-Reg States And Holds Back Autoimmune Disorders

by on August 18, 2014
When pathogens invade the body, the immune system kicks into gear and sends out swarms of cells to fight the invader.  These swarms consist of two types of cells; fighters, known as killer T cells, and peacemakers, known as regulatory T cells, sometimes referred to as Tregs.  The purpose of the Tregs is to send […]

Megascale 1.2 Kilometer Tall Icebergs Touched Arctic Sea Bed 800,000 Years Ago

by on August 17, 2014
Geoscientists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research report evidence that gigantic icebergs once towered 1.2 kilometers high and reached 1000 meters into the Arctic Sea to the bottom where they scoured deep tracks during a recent glacial period.  The tracks were found between Greenland (part of Denmark) and the […]

White Dwarf Progenitor Remarkably Caught By Telescopes Before Its Supernova

by on August 17, 2014
A team of astronomers from institutions including Rutgers University and Aarhus University in Denmark accomplished a very rare feat: they were able to monitor and identify a “progenitor” star before it had even turned supernova, by exploiting the fact that the Hubble Telescope was fortuitously observing the same region of the sky as they had […]

Tests Show Contrary To Folklore Magpies Do Not Like Shiny Objects

by on August 16, 2014
Psychologists at the Centre for Research in Animal Behavior (CRAB), located in the University of Exeter, completed a new study that counters the negative superstitions of magpies as having a penchant for being attracted to and stealing shiny things.  Instead, magpies treat new shiny things as they would new dull things, with fear. Europeans widely […]

Deletion Of Key Mitochondrial Gene Rewires Metabolism And Protects Against Age-Related Conditions In Mice

by on August 16, 2014
Molecular biologists and physician scientists at the Wistar Institute and Thomas Jefferson University in Philadelphia have discovered that deletion of a mitochondrial protein TRAP-1 rewires the metabolic network of mice, resulting in altered energy usage as well as attendant effects in reducing age-related pathologies such as obesity, inflammatory tissue degeneration, dysplasia, and spontaneous tumor formation. The […]
